CYLINDER BLOCK
Revision: 2006 November2007 350Z
Piston Pin Outer Diameter
Measure the outer diameter of piston pin with micrometer.
Connecting Rod Bushing Oil Clearance
(Connecting rod bushing oil clearance) = (Connecting rod bushing inner diameter) – (Piston pin outer diame-
ter)

If the measured value exceeds the limit, replace connecting rod assembly and/or piston and piston pin
assembly.

If replacing piston and piston pin assembly, refer to EM-119, "HOW TO SELECT PISTON" .

If replacing connecting rod assembly, refer to EM-131, "CONNECTING ROD BEARING OIL CLEAR-
ANCE" to select the connecting rod bearing.
Factory installed parts grading:

Service parts apply only to grade “0”.

CYLINDER BLOCK DISTORTION

Using scraper, remove gasket on the cylinder block surface, and also remove engine oil, scale, carbon, or
other contamination.
CAUTION:
Be careful not to allow gasket flakes to enter engine oil or engine coolant passages.Standard : 21.989 - 22.001 mm (0.8657 - 0.8662 in)
